Review: Great STEM toy! - Great STEM toy. My 6-year old grandson loves to build the circuits clearly illustrated in the included booklet. The instructions are very clear and easy to understand, allowing even a 6-year old build the many projects taught. My grandson becomes very excited to see the results of the circuits, including activation of lights, the turning and flying of included plastic fans, etc. If the child being gifted with this product has any interest at all in engineering, including mechanics and electricity, he/she will love it!
Review: Bought this for my niece for Christmas - I bought this for my niece for Christmas and it was her favorite gift by far. She immediately wanted to stop opening presents and start building with this kit. We spent a couple of hours that night building at least half the project in the included book. Shes 7 and I'm 30 and we were both having a great time. The radio was pretty neat. My brother tells me that is on of her favorite toys now and she want's to play with it all the time. Overall the kit is well thought out the instructions are pretty good. The biggest issue that I had with the kit was that some of the pieces (notably the logic boards) have an orientation to them and the markings on them that show this are sometimes difficult even for me to discern. Secondly although the instructions are great with lots of pictures they need a better way of illustrating the layers, I could figure it out but my niece was having a hard time with it... Overall even with those minor complaints this is an excellent product, I will be buying more of these in the future. Its so important to teach the sciences to young minds.

### ⭐⭐⭐⭐ Cool toy
*by K***B on June 1, 2025*

Great toy but one crucial piece in the set seems to be broken which really frustrated my son who then abandoned the toy. But great if everything works.
